Is it possible to turn 2D polylines into 3D polylines using elevations in text?

[Anonymous]

Hey everybody,

I need to have 3D Polylines in order to modify my existing surface by adding rupture lines so the triangulation doesn't go where it is not wanted. The thing is that my existing polylines are at the elevation 0. 

Is there a trick to fix the text elevations to the peak points of the 2D Polylines and transform them to 3D? 

Thanks for your help.

One thing you could do is create a feature line from the polyline and edit the elevations of the feature line in the elevation editor.  You can then explode the feature line to turn it back into a polyline.

That is a good trick, but the thing is that I'm trying to avoid to have to insert all elevations manually because I have to do this to 15 different projects...

Any other ideas? 🙂

have you tried proximity break line?

there is no silver bullet if you need to model 3d the input has to come from somewhere

Well, you could try to drape the 2D poly on the C3D surface:

1] transform the poly into feature with _CREATEFEATURELINES
2] then _AECCFEATUREELEVSFROMSURF
3] if you now select the feature, it should project on the existing C3D surface
4] finally, explode it twice, to get a 3Dpoly
